Figure 1.

Output of an ‘exonization’ query. The query was conducted using genes NM_015833, NM_032589 from chromosome 21 and NM_016083, NM_031483 from chromosome 20. Alus containing 3′ splice sites are shown at the top; Alus containing 5′ splice sites are at the bottom. Twenty nucleotides either side of splice sites are shown (the window width was a parameter of the query). The results include (from left to right): accession number, Alu ID in AluGene, Alu subfamily, orientation of the Alu versus the gene, exon number, total exons in the gene and sequences of Alus at the splice sites. The consensus sequences for each multiple sequence alignment are shown in the bottom-most rows.
